直埋電纜敷設有哪些要求

直埋高壓電纜敷設有一些需求？（1）頂管施工的溝底是綿軟的巖層，若果是鵝卵石或聚氯乙烯塑料臟物要鋪100mm厚的軟土或砂層。高壓電線數據線四周的和泥土如帶有灼傷高壓電線數據線合金包皮，應除掉和換土，埋深應不低于0.7m，空間穿越耕地中應不低于1m。在帶來古建筑材料設計物、與半地埋古建筑材料設計物雙向及破解半地埋古建筑材料設計物處，可淺埋，但應遵循保護好政策，高壓電線數據線應埋于凍巖層一下，當受的條件限止時，應遵循嚴防高壓電線數據線由于磨損的政策。（2）電力高壓電纜敷設后，中要鋪100mm厚的軟土或細砂，再蓋住瀝青水泥地面土維護板，履蓋長寬應超電力高壓電纜下方任何各50mm，或用磚用于瀝青水泥地面土維護板。

（3）間管(guan)接頭(tou)盒(he)在(zai)(zai)(zai)(zai)外(wai)(wai)(wai)(wai)面(mian)(mian)要(yao)有球(qiu)鐵或(huo)(huo)瀝青水泥地面(mian)(mian)土保(bao)證盒(he)。（4）插頭(tou)中間應(ying)墊以鋼筋混凝(ning)土土條(tiao)件板，高度要(yao)抬起插頭(tou)保(bao)護好(hao)盒(he)兩端600?700mm，電(dian)(dian)(dian)(dian)覽自土溝人才(cai)引進(jin)鐵路橋(qiao)、人孔和工程(cheng)物時(shi)，要(yao)穿(chuan)在(zai)(zai)(zai)(zai)分液漏(lou)斗(dou)，并將管(guan)接頭(tou)賭塞，制(zhi)止(zhi)冒(mao)水。（5）電(dian)(dian)(dian)(dian)攬線(xian)相互(hu)間是交差(cha)，或(huo)(huo)非熱(re)電(dian)(dian)(dian)(dian)廠管(guan)和水管(guan)是交差(cha)，時(shi)光穿(chuan)越一級公路和墻壁(bi)等(deng)元素(su)時(shi)，都(dou)需要(yao)穿(chuan)在(zai)(zai)(zai)(zai)保(bao)養分液漏(lou)斗(dou)，保(bao)養管(guan)長(chang)寬少于(yu)是交差(cha)點1m，是交差(cha)凈距不宜乘以250mm，保(bao)養管(guan)直徑(jing)(jing)不宜乘以電(dian)(dian)(dian)(dian)攬線(xian)外(wai)(wai)(wai)(wai)徑(jing)(jing)的1.5倍。（6）直埋電(dian)(dian)(dian)(dian)攬普遍選擇(ze)鎧(kai)裝電(dian)(dian)(dian)(dian)攬。在(zai)(zai)(zai)(zai)鎧(kai)裝電(dian)(dian)(dian)(dian)攬的金(jin)(jin)屬材料(liao)外(wai)(wai)(wai)(wai)皮兩端要(yao)安全(quan)可靠跨(kua)接系(xi)統，跨(kua)接系(xi)統電(dian)(dian)(dian)(dian)阻功率不能超出(chu)10Ω。（7）直埋電(dian)(dian)(dian)(dian)覽在(zai)(zai)(zai)(zai)美段每間隔50?100m處，電(dian)(dian)(dian)(dian)覽金(jin)(jin)屬接頭(tou)處、轉彎處、進(jin)入施工物等(deng)處，應(ying)設(she)施顯(xian)然的方(fang)向位置標簽或(huo)(huo)標樁。（8）通信低壓電(dian)(dian)(dian)(dian)纜(lan)與另外(wai)(wai)(wai)(wai)熱(re)力(li)(li)途徑(jing)(jing)、發展、房屋地下建筑等(deng)相互(hu)形成平行(xing)線(xian)線(xian)和相互(hu)時(shi)的小凈距，應(ying)適(shi)用規(gui)程(cheng)法律法規(gui)。不得將通信低壓電(dian)(dian)(dian)(dian)纜(lan)形成平行(xing)線(xian)線(xian)敷設(she)于(yu)熱(re)力(li)(li)途徑(jing)(jing)的上邊或(huo)(huo)評論。
